Why these books
A real curriculum, in kid-sized chapters.
01
Forty books that grow with one child
Kit grows up across three series and six years. So does your reader. Buy one book, one collection, or commit to the whole journey, and never run out of the next right thing to read.
02
Real concepts, taught honestly
Trademarks, copyrights, patents, trade secrets: the four pillars of intellectual property, taught not as vocabulary but as stories a four-year-old can use. Written by an engineer and patent attorney.
03
Built for the way kids actually learn
Board pages for tiny hands. Picture-book workshops for kindergarten thumbs. Chapter books with journal pages for grade-school imaginations. Right format, right age, every step.
Series 1 · Kit's Little Sparks · Ages 2 to 4
The journey begins in 20 board books.
Series 1 walks a child through five gentle phases of the inventor's mindset. Buy one phase, one book, or the whole series. Free read-along audio and activity sheets included with every title.
01
Books 1 to 4
Wondering
Kit's eyes open. Notice the world. See that everything was made by someone. Spot the puzzles. Name the feelings.
02
Books 5 to 8
Making
Crayons and cardboard come out. Kit draws, builds, fails, tries again, and improves an idea one fix at a time.
03
Books 9 to 12
Sharing
Things get names. "I made that" gets a proud voice. Sharing finds its rules. A special stamp says: this is mine.
04
Books 13 to 16
Growing Together
Copycats happen. So does collaboration. Kit handles them with words, builds with friends, and gives something away.
05
Books 17 to 20
Becoming
A child stands up and tells the world what they made. Inspired by inventors before them. Teaching the next little sister.
A year-and-a-half of read-alouds. One growing reader.
The first chapter of an inventor's life.

The Founder
Why a patent attorney built a 40-book children's library.
I've spent 30 years working with inventors. I've helped people patent everything from automotive components to medical devices, and what I learned across all those projects is that invention isn't a talent. It's a process. Notice. Sketch. Try. Fail. Fix. Show. Claim.
In 2015 I co-founded a preschool. And every single day I watched 3-year-olds run that exact same process. Cardboard. Tape. Trial and error. Big claims about what they'd just built. The same arc I'd been documenting for grown-up inventors my whole career.
Kit's Big Ideas is the library I wished existed: forty books across three age-tiered series, designed to plant the inventor's mindset at age 2, hand a child the tools at age 4, and put them to work at age 6. Series 1 is here. Series 2 and Series 3 are in the works. Sign up for the first-look list and I'll let you know the moment each one is ready.

Questions
Things parents actually ask.
How does the 40-book universe actually work?
Three age-tiered series under one growing journey. Series 1 (Kit's Little Sparks · 20 board books · ages 2 to 4) is shipping now. Series 2 (Inventor Workshop · 10 picture books · ages 4 to 6) and Series 3 (Inventor's Journal · 10 chapter books · ages 6 to 8) are in the works. Sign up for the first-look list to be notified the moment each one is ready, no commitments. A child who starts at age 2 grows into the next series the year they outgrow the last.
What age is Series 1 really for?
Designed for ages 2 to 4. The early books work as read-alouds for 18-month-olds; the later books support pre-K conversations. Many families read the same book at 2 and again at 4, different layers come out as the child grows.
Are the print copies actually durable?
Series 1 ships as full board books with thick, glossy pages, built for the way toddlers actually treat books. Series 2 will be standard picture books (ages 4 to 6 are gentler). Series 3 will be illustrated chapter books with a hardcover edition.
Is there a free read-along audio version?
Yes, every Series 1 book ships with a free read-along audio version, available on this site and on the Little Sparks Books YouTube channel. Press play, listen along with your child, and follow the printed book or the on-screen pages.
Can I pre-order Series 2 or 3?
Not yet, Series 2 and 3 are still in the works. Joining the first-look list is the easiest way to be notified the moment each one is ready. No commitments, no charges, just a heads-up.
Do you offer educator or library pricing?
Yes. 20% off educator orders of 20+ books, 25% off at 100+. Free educator guides come with every book. Request a sample pack at the link in the educator section.
